Microsoft announced their latest operating system, Windows 10, at an event in San Francisco on September 30th, 2014. It is the first major Windows release since Windows 8 debuted in 2012. The new operating system will introduce new features as well as bring back features that were left out of Windows 8 like the Start Menu and the ability to run an application without it being full-screen.

The Windows 10 Technical Preview is available now for developers, but a public release date for the official version of Windows 10 has not been set.
